The man who has sued "X-Men" director Bryan Singer -- claiming he was sexually assaulted when he was 15 -- has just filed lawsuits against 3 other Hollywood big wigs, also claiming sexual assault.

The 3 men named in the new lawsuit are Garth Ancier, David Neuman and Gary Goddard.

Ancier has a slew of hits under his belt, including The Ricki Lake Show, which he created. He headed up the Fox entertainment group and produced 21 Jump Street, Married ... with Children, TheSimpsons and In Living Color. He also developed Home Improvement at Disney. And at NBC he put The West Wing on the air.

Neuman is the former president of Disney TV. Goddard produced off-Broadway shows.

According to the new lawsuits, Ancier sexually abused Egan numerous times by sodomizing him, forcing oral sex and fondling him -- when he was 15 at an Encino estate. The suit goes on to allege Ancier sexually abused Egan in Hawaii 2 years later.

The suit against Goddard and Neuman are similar -- alleging they were part of a Hollywood sex ring, giving Egan alcohol and drugs and sexually assaulted him at the Encino estate and in Hawaii.

Michael Egan -- now 31 -- and his lawyer, Jeff Herman are holding a news conference detailing the new allegations.

Egan's mother, Bonnie, sobbed uncontrollably as she tried explaining why she let her son go to adult parties and on trips to Hawaii. She said the alleged abusers seemed like nice people.

The state of Hawaii has allowed alleged victims of sexual assault to sue, even if the statute of limitations has long since expired -- but the deadline for filing is Thursday.
